Detailed Description
The following describes embodiments of the present invention in detail.
The cleaning agent for the interior of the air conditioning system is non-toxic and environment-friendly, cannot damage an ozone layer, is non-flammable and high in safety, and cannot damage the system in the using process; it comprises a first solvent, a second solvent and a third solvent which are mixed in any proportion (weight percentage); wherein,
the first solvent is tetrafluoroethane, is used for controlling the overall flammability of the cleaning agent, and is used as a propellant when in a gaseous state;
the second solvent is 1,1,1,3, 3-pentafluorobutane, which is used as a cleaning solvent and has flammability;
the third solvent is trans-1, 2-dichloroethylene, has corrosivity, is used as a cleaning solution and has flammability;
the first solvent, tetrafluoroethane, alias R134a, HFC134a, HFC-134a, chemical name 1,1,1, 2-tetrafluoroethane, CAS number 811-97-2, chemical formula CH2FCF3, is non-toxic, non-flammable, has a boiling point at atmospheric pressure of-26.3 ℃, is a haloalkane refrigerant with similar thermodynamic properties to difluorodichloromethane (R-12), but has a lower ozone destruction potential than R-12. As the most widely used medium-low temperature environment-friendly refrigerant, the tetrafluoroethane becomes a very effective and safe substitute of CFC-12 due to the good comprehensive performance of HFC-134a, and is mainly applied to most fields using R-12(R12, Freon 12, F-12, CFC-12, Freon 12 and dichlorodifluoromethane) refrigerants, including: the composite material can be used in refrigeration equipment such as refrigerators, freezers, water dispensers, automobile air conditioners, central air conditioners, dehumidifiers, refrigeration houses, commercial refrigeration, water freezers, ice cream machines, freezing and condensing units and the like, and can also be applied to aerosol propellants, medical aerosols, pesticide propellants, polymer (plastic) physical foaming agents, magnesium alloy protective gases and the like.
1,1,1,3, 3-pentafluorobutane, CAS number 406-58-6, formula C4H5F 5.
Trans-1, 2-dichloroethylene, CAS No. 156-60-5, chemical formula C2H2Cl2, is colorless and slightly odorous, volatile liquid, is flammable, and the vapor and air can form explosive mixtures which can cause combustion and explosion when meeting open fire and high heat energy. At the same time, dichloroethylene has certain aggressive properties and at sufficiently high concentrations may be detrimental to the integrity of plastics and polymers, but when combined with certain fluorine-containing hydrocarbons, the solvent is less aggressive.
It will be appreciated by those skilled in the art that 1,1,1,3, 3-pentafluorobutane and trans-1, 2-dichloroethylene are flammable and that a disadvantage of these two combinations is that the combination of these ingredients produces another flammable mixture and therefore its use has certain limitations.
However, the use of tetrafluoroethane reduces the overall flammability of the cleaner, while providing additional solvent characteristics that render the solvent non-flammable, thereby increasing the range of use of the cleaner. The cleaning agent solution prepared according to the specific proportion of the solvent can be changed to adapt to different use working conditions. Meanwhile, the tetrafluoroethane has the function of a propellant, so that the cleaning agent can automatically flow and clean in the pipeline without the help of an external circulating pump, and the pipeline is simpler to clean. And tetrafluoroethane as a propellant can produce a setting action; the flammability of the cleaning agent can be reduced, and the cleaning agent has the function of a propellant and can generate solidification.
Different examples are provided below according to the component ratios, and the examples differ only in the ratio.
According to different proportion, the cleaning agent has different balance points among cleaning effect, fireproof property, corrosivity, propelling effect and coagulability; the present invention aims to find the best balance point among the performances.
In the first embodiment, the cleaning agent comprises the following components in percentage by weight:
tetrafluoroethane: 10% -30%;
1,1,1,3, 3-pentafluorobutane: 5% -25%;
trans-1, 2-dichloroethylene: 45 to 75 percent.
The second embodiment comprises the following components in percentage by weight:
tetrafluoroethane: 15% -25%;
1,1,1,3, 3-pentafluorobutane: 10% -20%;
trans-1, 2-dichloroethylene: 50 to 70 percent.
In the third embodiment, the cleaning agent comprises the following components in percentage by weight:
tetrafluoroethane: 18% -20%;
1,1,1,3, 3-pentafluorobutane: 15% -20%;
trans-1, 2-dichloroethylene: 60 to 70 percent.
The fourth embodiment comprises the following components in percentage by weight:
tetrafluoroethane: 19 percent;
1,1,1,3, 3-pentafluorobutane: 18 percent;
trans-1, 2-dichloroethylene: and 63 percent.
In the fifth embodiment, the cleaning agent comprises the following components in percentage by weight:
tetrafluoroethane: 18.6 percent;
1,1,1,3, 3-pentafluorobutane: 17.3 percent;
trans-1, 2-dichloroethylene: 64.1 percent.
When the cleaning agent contains 5% -25% of pentafluorobutane and 45% -75% of trans-1, 2-dichloroethylene, 10% -30% of tetrafluoroethane is needed to achieve complete or complete fire resistance; further, when the cleaning agent contains 10% -20% of pentafluorobutane and 50% -70% of trans-1, 2-dichloroethylene, 15% -25% of tetrafluoroethane is needed to achieve complete or complete fire resistance; when the cleaning agent contains 15% -20% of pentafluorobutane and 60% -70% of trans-1, 2-dichloroethylene, 18% -20% of tetrafluoroethane is needed to achieve complete or complete fire resistance; further, when the cleaning agent contains 18% of pentafluorobutane and 63% of trans-1, 2-dichloroethylene, and when the cleaning agent contains 19% of tetrafluoroethane, the cleaning agent has the best cleaning effect and fire resistance, and the corrosivity, the propellant effect and the coagulability are in good states; when the cleaning agent contains 64.1 percent of trans-1, 2-dichloroethylene, 17.3 percent of 1,1,1,3, 3-pentafluorobutane and 18.6 percent of tetrafluoroethane, the cleaning effect is excellent, the cleaning agent is non-flammable and has good fireproof property, and meanwhile, under the action of no external force, the cleaning agent automatically flows in a pipeline to clean by a propellant carried by the cleaning agent, the cleaning effect is good, and unnecessary acidic substances and pollutants in the pipeline can be removed.
The cleaning agent for the interior of the air conditioning system is simple in component, convenient to prepare, low in manufacturing cost, environment-friendly, non-toxic, environment-friendly, safe and convenient to use, does not damage an ozone layer, is non-combustible, and cannot damage the system in the using process.
